At [FOSDEM 2024](https://fosdem.org/2024), LLVM will again participate with a dedicated devroom, on Sunday afternoon February 4th, in Brussels. As possibly the largest European Open Source Conference, FOSDEM attracts more than 600 lectures and over 8000 hackers - many core contributors of the world’s leading open source projects. Complementing the LLVM developer meetings, the devroom at FOSDEM provides a great opportunity for LLVM developers and the wider open source community to get together, connect and discuss. For the first time, there is also a gcc devroom, which is happening on the same day, right before the LLVM dev room. We invite academic, industrial and hobbyist speakers to present their work on developing or using LLVM, Clang, LLDB, Compiler-rt, MLIR, Flang, or any of the other technologies in the LLVM project. We are looking for: * Keynote speakers. * Technical presentations (default length of 30 minutes including questions) related to the development of LLVM technologies or use of those technologies in other projects. * Tutorials. * Lightning talks (default length of 5 minutes). * Demos. ### Submission Please submit your proposal through the [FOSDEM pretalx interface]( https://pretalx.fosdem.org/fosdem-2024/cfp), clicking the "Submit a proposal" button. Please make sure you select "LLVM" as the "Track”. By default we will assume you submit a proposal for a full talk, aiming for 20 minutes of presenting and 10 minutes of questions. If you propose a different kind of talk and would prefer a different length, please do clearly state so in the "Submission Notes" field. We optimize the length of individual presentations taking into account all submissions and preferred length to achieve the best possible overall program. Presentations will be recorded and streamed. Sending your proposal implies giving permission to be recorded. This year, FOSDEM only accepts in-person presentations, with a live stream and live chat for remote participants. The deadline for receiving proposals is December 1st, 2023. Speakers will be notified of acceptance or rejection by December 15th. Please find some advice on what constitutes a good proposal at the end of this CFP. ### Registration FOSDEM does not require any registration and is free of charge. All participants need to follow the [FOSDEM Code of Conduct]( https://fosdem.org/2024/practical/conduct/). ### Important Dates * December 1st 2023: Deadline for submission of proposals * December 15th 2023: Announcement of acceptance + final schedule * February 4th 2024: Devroom day, in-person in Brussels. We expect the dev room to run from 1pm until 5pm. ### Organization Please use [this LLVM Discourse thread]( https://discourse.llvm.org/t/cfp-fosdem-2024-llvm-dev-room/74823) to discuss any issues or questions related to submitting a proposal or the organisation of the event. ### Guidance on writing a proposal for the LLVM Dev Room This is a guide to help you submit a good proposal and increase your chances of your proposal being accepted. If you have never presented at an LLVM meeting, then do not fear this process. We are actively looking for new speakers who are excited about LLVM and helping grow the community through these educational talks! You do not need to be a long time developer to submit a proposal. The programs of the FOSDEM LLVM dev room from past years can give you an impression of what an abstract can look like: [2023]( https://archive.fosdem.org/2023/schedule/track/llvm/) [2022]( https://archive.fosdem.org/2022/schedule/track/llvm/) [2020]( https://archive.fosdem.org/2020/schedule/track/llvm/) [2019]( https://archive.fosdem.org/2019/schedule/track/llvm/) [2018]( https://archive.fosdem.org/2018/schedule/track/llvm_toolchain/) [2017]( https://archive.fosdem.org/2017/schedule/track/llvm_toolchain/) [2016]( https://archive.fosdem.org/2016/schedule/track/llvm_toolchain/) [2015]( https://archive.fosdem.org/2015/schedule/track/llvm_toolchain/) [2014]( https://archive.fosdem.org/2014/schedule/track/llvm/) #### General Guidelines: * It should be clear from your abstract what your topic is, who your target audience is, and what are the takeaways for attendees. The program committee does not have time to read 10 page papers for each submission. * Talks about the use of an LLVM technology should include details about how LLVM is used and not only be about the resulting application. * Tutorials on “how to use X” in LLVM (or other subproject) are greatly desired and beneficial to many developers. Entry level topics are encouraged as well. * Typically a few paragraphs is sufficient. Best regards, the LLVM @ FOSDEM organisers
